Allora Ioram disse: «Attacca!». E si attaccò il suo carro. E Ioram, re d'Israele, e Acazia, re di Giuda, uscirono ciascuno sul proprio carro; uscirono incontro a Iehu e lo trovarono nel campo di Nabot l'Izreelita.
Rashi
the blood of Jezreel To be understood according to its Aramaic translation: the blood of the house of Ahab, whom Jehu slew in Jezreel because they worshipped Baal, and he and his sons went afterwards and worshipped pagan deities; therefore, I account for them the blood of the house of Ahab as innocent blood.
